at o'rileys if you are going out to use it in the lot they just take your ID and a Credit card and they give them back once you return the scanner
Just scanned my engine light and it also read p0300. Replacing the coil this afternoon. Hopefully I haven't damaged the cat.
Just replaced the coil pack. I am still experiencing hesitation and a occasional misfires. Do I need to replace the plugs and wires as well. I'm just wondering if there is anything else I should try. I am not getting an engine light but I can tell its not running properly.
Unfortunately misfire can be caused by many things. If you start hanging parts, you may spend quite a bit of $$ before the problem gets resolved. Best to diagnose first but OTOH, plugs and wires are basic maintenance, so depending on how many miles are on them, it might be a good thing to try next. If that doesn't work, you should get some systematic testing done.
